Equipment Specifications and Methods for Dynamic Testing

چکیده
Both the new ASAE S518 standard (2) and the revised draft international standard DIS/ISO 5707 (3) incorporate performance standards for vacuum stability in milking systems. New NMC procedures for system evaluation include dynamic tests for vacuum stability to demonstrate the adequacy of new or existing milking systems (7) . Such dynamic (i.e. "milking-time") tests require the use of test instruments with response characteristics which are appropriate for the measurement of expected rates of vacuum change in a milking system.

Development of a compression system dynamic simulation code for testing and designing of anti-surge control system
In recent years, several research activities have been conducted to develop knowledge in analysis, design and optimization of compressor anti-surge control system. Since the anti-surge control testing on a full-scale compressor is limited to possible consequences of failure, and also the experimental facility can be expensive to set up control strategies and logic, design process often involves...

As part of the development of equipment and innovative technology for the process flow-sheet, a study on the selection of good resin for uranium uptake is ongoing. Both static and dynamic column equilibrium testing upon synthetic and Gattar pregnant leach solutions (PLS) were carried out to estimate the change of total capacity and breakthrough capacity of the commercial macroporous anion excha...
متن کاملEvaluation of Dynamic Probing Testing Effect in Hand Excavated Pit on Test Results Using Numerical Modeling
In Iran, using the hand excavated pits (wells) have been more common compared to other countries. As a matter of fact, recent years, utilizing the dynamic probing test (DPT) in these types of pits has been significantly developed in Iran. This is while the standard state of doing this test is from the ground level. In this work, the dynamic probing test is carried out in two similar wells with ...
متن کاملCost Analysis of Acceptance Sampling Models Using Dynamic Programming and Bayesian Inference Considering Inspection Errors
Acceptance Sampling models have been widely applied in companies for the inspection and testing the raw material as well as the final products. A number of lots of the items are produced in a day in the industries so it may be impossible to inspect/test each item in a lot. The acceptance sampling models only provide the guarantee for the producer and consumer that the items in the lots are acco...
متن کاملFrom converter characteristics to built-in self-test proposals
Converter testing is a complex process. Test specifications are application dependent and in most cases require sophisticated stimulus generation and, response analysis equipment. The processing of sampled data to generate specification measurements also requires complex DSP algorithms. Furthermore, test complexity increases with speed, resolution and technology advances. This chapter summaries...
